G. BUHLMANN. WARP KNITTING MACHINE.
Patented 004. 25, 1892.

UNITED STATES PATENT OFFICE.
GEORG 'BUHLMANN, OF BERLIN, GERMANY.
WARP-KNITTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 484,844, dated October 2 1892.
Application filed May 12, 1892. Serial No. 432,760. (No model.)
To all whom it may concern:
Be it known that I, GEORG BUHLMANN, a subject of the King of Prussia, German Emperor, and a resident of Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Warp-Knitting Machines, of which the following is an exact specification.
The object of my invention is to provide such parts on a warp-knitting machine that fabrics resembling plush may be produced by the same; and my invention consists in adding to a warp-knitting machine of usual construction a suitable looper round which the pile-threads are laid. I may also combine with the said looper a knife, serving to sever the pile-threads after the loops have been formed, whereby the nap is produced, giving to the fabric a velvet-like appearance. The loops of the pile-threads may, however, remain as such, and in this case the knife is dispensed with.
In order to make my meaning clear, I have appended hereunto a sheet of drawings, on which Figure 1 is a sectional elevation of my improved machine. Fig. 2 is a sectional plan taken on line so a: of Fig. 1. Fig. 3 is a front elevation, the warp-thread holder and the upper part of the machine being omitted.
Similar letters denote similar parts throughout the several views.
The construction of the warp-knitting machine is in its main parts the usual one.
'11 arethe knitting-needles, movingto andfro.
r is the warp-thread holder, moving laterally in a direction perpendicular to the needles n and having, also, an intermittent oscillating motion round the rod 19, as indicated on Fig. 1. This holder is at its front end provided with holes, through which the Warp-threads are passed.
h are the pile-thread holders, each being a short sleeve, and g are the weft-thread guides. Both parts It and g are secured to bars which are moved laterally to and fro in the'same direction as the Warp-thread holder 1'. The holders h and guides g are removable, so that any required number of the same may be mounted on the said laterally-movable bars,
according to the breadth of the fabric to be produced.
it are the warp-threads.
m are the pile-threads, and w the Weftthreads.
8 is a stop preventing the warp-threads from moving too high.
Q; is a rod on which the fabric rests.--
As will be seen in Fig. 3, I secure to the frame of the machine a series of vertical bars 17, the lower ends of which I prefer to make tapering, and which serve to form the loops of the pile-threads m; wherefore I have called them loopers. lVhen it is desired to out the pile-threads after having formed the loops, I make the looper b tubular at' its end and arrange a knife 0 below the same, the point of said knife entering the looper b. The loopers b and the knives o are secured to the frame of the machine, and are not displaced together with the other parts of the same.
The operation of the machine is the following: The warp-threads and weft-threads are interknit into one another in the usual manner by the reciprocating movement of the needles n and by the lateral displacement of the warp-thread guide 1" and the weft-thread guides g, so that the needles n pass alternately on different sides of the Weft-threads w. At the same time the pile-threads m are moved sidewise, and thus laid around the looper b. At the next movement of the needles n the pile-threads m are completely formed into loops, being drawn backward at the backward movement of the needles by the warpthreads caught in the eyes of the same, and at the same time they are interknit into the ground formed by the warp-threads 7c and the weft-threads w. The latter may of course also be formed by ornamented stringsor bands. In consequence of the tapering form of the looper b the loop of the pile-threads m glides down along said looper, this movement being facilitated by the downward movement of the warp-thread holder 0". Thus when the knife 0 is not employed the loops of the pile-threads will gradually slip off the looper Z), and thus a band or course of a looped fabric is produced. When the knifeois placed below the looper b, the loops of the pile-threads We cannot glide off,
but are cut by the edge of the knife 0, whereby the fabric of plush or velvet-like appearance is obtained. The pull of the fabric, which is delivered in the direction indicated on Fig. 1, is sufficient to cause the pile-threads to be severed by the knife 0.
It is obvious that the knives 0 are removable, so that the Warp-knitting machine may be employed, as desired, for the manufacture of one or the other kind of fabrics mentioned above.
Having thus fully described the nature of my invention, what I desire to secure by Letters Patent of the United States is- 1. In a warp-knitting machine, the combination, with the needles 'n, Warp-guides r, and
